The image performance of a negative index slab and a layered slab using coupled surface modes
This paper reviews the concept of high-resolution imaging of a negative index material (NIM) slab and compares its performance with the structure made based on the idea of coupled surface-modes layers...

An approach to develop room temperature detectors is to use transitions between the light/heavy hole bands and the split-off hole band to produce enhanced response at high temperature. Results are presented on a theoretical model to predict the response in these split-off detectors. The model calculates the dark and illuminated currents from the photoabsorption, carrier escape, and transport, explaining the experimental response. The variation in dark current, responsivity, and D* with the detector parameters is presented.
